Description

The present invention relates to eyeglass frames and eye mirror temple portion is connected to the lens side.

  Currently, various eyeglass frames are commercially available, and for example, those described in Patent Document 1 are known. This eyeglass frame is formed by connecting a front part and a temple part, each made of plastic, with a metal hinge. In this case, the hinge is fixed to the front portion, the rod-like portion extending from the hinge is inserted into the receiving hole of the temple portion, and in this state, both are fixed with screws or the like.

On the other hand, when connecting a metal hinge to a plastic eyeglass frame, most of the commercially available eyeglasses usually have a relatively shallow receiving hole in the temple part, and a rod-shaped part on the hinge side is inserted into this. Then, both are fixed with an adhesive.
JP-T 9-504880

  By the way, as a material of the eyeglass frame, there are some which use animal horns or sharks. When the temple portion is made of such a material, in the connection method described in Patent Document 1, the rod-shaped portion of the hinge is repeatedly brought into contact with the wall surface of the receiving hole as the wearer walks. Due to this contact, the wall surface of the receiving hole is worn, and there is a risk that the wearing feeling of the glasses will be lost over time.

  On the other hand, if a fixing method using an adhesive is employed, it is possible to prevent wear at a temple portion made of Sakai. However, since the adhesive is used, when the temple portion is damaged, it is not possible to replace only the temple portion.

  Therefore, it is conceivable to stop using the adhesive with an emphasis on exchangeability, but in this case, since the hinge is likely to fall off at a relatively shallow receiving hole, it is necessary to increase the depth of the receiving hole. However, in the case of materials such as animal horns and shells, it is more difficult to break during processing than plastic, so it is difficult to drill deeply into the receiving hole, and the above-mentioned problem of wear still remains. Such a problem is considered to occur not only in the case of a spectacle frame but also in the case of manufacturing an accessory by connecting members such as those made by Sakai.

  The present invention has been made in view of the above problems, and the target eyeglass frame and eyeglasses can be processed and exchanged even when a material such as an armor is used as a frame material. In addition, the wear can be suppressed.

  The eyeglass frame of the present invention that achieves the above object is a temple part configured to be opened and closed by a hinge with respect to the lens side, a receiving hole formed in the temple part, and formed in the hinge from the hinge to the temple part. And a projecting portion that extends into the receiving hole and further includes a holding member made of a material that is more flexible than the hinge and temple portion, and the projecting portion is inserted into the receiving hole together with the retaining member. In this state, it is removably held in the receiving hole.

  According to the present invention, the temple part can be handled as a separate body with respect to the hinge by removing the protruding part from the receiving hole, so that the exchangeability of the temple part can be improved. Further, in the inserted state, the holding member can come into contact with the wall surface and the protruding portion of the receiving hole like a cushion, so that these wears can be suppressed. In addition, since the protrusion is held in the receiving hole in the connected state, the depth of the receiving hole does not need to be relatively large. Thereby, even if a shell or the like is used as the material of the temple portion, the workability of the receiving hole is not impaired.

  Preferably, when the protruding portion is inserted into the receiving hole without the holding member, the protruding portion falls out of the receiving hole in a free state, whereas when the protruding portion is inserted into the receiving hole together with the holding member, the protruding portion is free from the receiving hole. It is good to be prevented from falling out.

  According to this configuration, by utilizing the flexibility of the holding member, it is possible to prevent the protruding portion from falling off in a free state without separately using a fixing component such as a screw or a screw.

  More preferably, the protruding portion is formed in a rod shape, and the holding member is formed in a cylindrical shape, and the protruding portion is attached to the inside and expands in the radial direction so as to be in close contact with the inner wall of the receiving hole.

  By doing so, it is possible to prevent the protruding portion from falling off in a free state with a simple configuration. On the other hand, when the protruding portion is pulled out with a force larger than the force applied in a free state, the flexible holding member is deformed by the pulling force, and the protruding portion can be extracted from the receiving hole.

  More preferably, the eyeglass frame of the present invention includes a rotation stop means including an engagement portion formed in the hinge and an engagement reception portion formed in the receiving hole, and the rotation stop means is the engagement portion in the connected state. It is good to prevent rotation of the temple part with respect to the hinge by engaging the engagement receiving part.

  According to this configuration, since the connected temple portion is locked to the hinge, the stability (preventing rattling) of the connected temple portion can be improved.

  Preferably, the material of the temple portion may be shell, wood, bamboo, animal horn or acetate.

  Even if it is such a raw material, a receiving hole can be formed, without impairing workability.

  Another eyeglass frame of the present invention that achieves the above object is the one in which the temple part is connected to the front part on the lens side by the connecting means, and the connecting means includes a receiving hole formed in one of the front part and the temple part, A protrusion that is in the other of the front part and the temple part and is inserted into the receiving hole; and a holding member made of a material that is more flexible than the front part and the temple part, and the protruding part is received together with the holding member. It is removably held in the receiving hole while being inserted into the hole.

  According to the present invention, similar to the above-described eyeglass frame of the present invention, not only can the temples and the front part be exchanged and the receiving holes can be processed, but also the wear of the wall surfaces of the receiving holes can be suppressed.

  The eyeglasses of the present invention are provided with the above-described eyeglass frame of the present invention.

In the accessory of the reference example , in which the second member is connected to the first member by the connecting means, the connecting means is in the receiving hole formed in the first member and the receiving hole in the second member. A protrusion that is inserted and a holding member made of a material that is more flexible than the first member and the second member. The protrusion is inserted into the receiving hole together with the holding member. It is removably held in the hole.

According to the reference example , even when a material such as an armor is used for the first member, the exchangeability of the first member and the second member is improved in the same manner as the eyeglass frame of the present invention described above. In addition, the workability of the receiving hole of the first member and the wear of the wall surface can be suppressed.
Here, examples of the accessory include brooches, pendants, earrings, earrings, bracelets, hair clips, loupes, and straps.

  According to the spectacle frame and spectacles of the present invention, since the holding member is inserted into the receiving hole, it is possible to improve workability and exchangeability while suppressing wear even when a material such as the upper is used for the frame material. it can.

  Hereinafter, with reference to the accompanying drawings, a description will be given of glasses equipped with a glasses frame according to a preferred embodiment of the present invention. In addition, since the structure of the spectacles is left-right symmetric, below, it demonstrates centering on the components of the left side, and abbreviate | omits description about the components of the right side suitably.

  As shown in FIG. 1, the glasses 1 include a glasses frame 2 and a pair of left and right lenses 3 and 3. The eyeglass frame 2 includes a front portion 10 on which the lenses 3 and 3 are mounted on the left and right sides, and a pair of left and right temple portions 12 and 12 that are put on the ears of the wearer.

The front portion 10 includes a rim frame 14, 14 that fixes the entire circumference of the lenses 3, 3, a bridge 16 that connects the inner portions of the rim frame 14, 14, and a rear portion from the inner portion of the rim frame 14, 14. The protruding nose pads 18 and 18 are integrally formed.
The temple parts 12, 12 extend rearward of the front part 10, and are configured to be openable and closable with respect to the front part 10 by hinges 20, 20.

  Various materials such as plastic, metal and natural materials can be used for the material of the front portion 10 and the temple portions 12 and 12, for example, celluloid, nylon, nickel alloy, titanium, aluminum, stainless steel, shell, animal horn ( Horn), wood, bamboo, and acetate. The eyeglass frame 2 of the present embodiment is suitable when natural materials such as the shell, animal horns, wood and bamboo, and acetate are used as materials. Below, the case where the front part 10 and the temple parts 12 and 12 are formed using the upper shell is demonstrated.

  2 and 3, the hinge 20 includes a fixed hinge piece 32 fixed to the rim frame 14, a movable hinge piece 34 movable with respect to the fixed hinge piece 32, a fixed hinge piece 32, and a movable hinge piece. And a projecting bar 38 projecting from the movable hinge piece 34. Here, metal is used as the material of the hinge 30.

  The front side of the fixed hinge piece 32 is fixed to the rear surface 14a of the outer portion of the rim frame 14 with, for example, an adhesive. A pair of upper and lower projecting pieces are formed on the back side of the fixed hinge piece 32, and the pair of projecting pieces are fastened together with screws 36 with a part of the movable hinge piece 34 sandwiched therebetween. Accordingly, the movable hinge piece 34 is configured to be rotatable about the screw 36, and the temple portion 12 can be opened and closed.

  The movable hinge piece 34 has an L-shaped piece in an L shape in plan view, a side surface 34a constituting one side of the L-shaped piece extends in the front-rear direction, and a back surface 34b constituting the other side is arranged in the left-right direction. It is extended.

  The protruding bar 38 extends from the back surface 34 b of the movable hinge piece 34 toward the temple portion 12 integrally therewith. The protruding bar 38 is formed in a round bar shape with a round cross section, and is sufficiently shorter than the length of the temple portion 12. As an example, the length of the protruding bar 38 is about 2 cm, which is about 1/5 to 1/7 of the length of the temple portion 12. The protruding bar 38 configured in this manner is inserted into a receiving hole 60 formed in the temple portion 12 with the holding tube 50 attached thereto.

  The holding tube 50 (holding member) has a cylindrical shape and has a thickness of about 1 mm, for example. The length of the holding tube 50 is the same length as the protruding bar 38. For this reason, when the holding tube 50 is mounted from the distal end side of the protruding bar 38, the back surface 34 b of the hinge 20 functions as a stopper that receives the end surface of the holding tube 50.

  The holding tube 50 is made of a material that is more flexible, stretchable, and elastic than the material of the protruding bar 38 and the temple portion 12. Examples of this type of material include silicon and vinyl chloride, but it is preferable to use silicon if importance is attached to the high adhesion between the protruding bar 38 and the temple portion 12.

  The inner diameter of the holding tube 50 is slightly smaller than the outer diameter of the protruding bar 38. For this reason, the holding tube 50 is attached to the protruding tube 38 so as to be pushed into the holding tube 50. In the state where the protruding bar 38 is attached, the holding tube 50 is expanded in the radial direction (see FIG. 3). It is preferable that the holding tube 50 has flexibility, stretchability, and elasticity to such an extent that the deformation of the holding tube 50 is ensured. Since the holding tube 50 is transparent or translucent, the position of the protruding bar 38 inside the holding tube 50 can be confirmed from the outside as shown in FIG.

  As shown in FIG. 4, the receiving hole 60 is formed as a recess that extends from one end surface 12 a of the temple portion 12 to a midpoint in the temple portion 12. The receiving hole 60 is formed by continuously forming two holes 62 and 64 having different depths and widths in the depth direction, and the relatively deep and narrow holding holes 62 are relatively shallow and wide counterbore holes. 64 is formed on the back side. The stepped receiving hole 60 is formed by drilling with a drill or the like.

  The holding hole 62 has a bottomed cylindrical shape. The holding hole 62 is formed corresponding to the protruding bar 38 and the holding tube 50, and has the same depth (length) as these lengths. Here, the inner diameter of the holding hole 62 is larger than the outer diameter of the protruding bar 38 and the inner diameter of the holding tube 50, but slightly smaller than these outer diameters when the holding tube 50 is mounted on the outer periphery of the protruding bar 38. It has become a thing.

Accordingly, when the protruding bar 38 and the holding tube 50 are each inserted into the holding hole 62 alone, they are not held in the holding hole 62, and therefore easily fall out of the holding hole 62 in a free state.
On the other hand, when the protruding bar 38 is inserted into the holding hole 62 together with the holding tube 50, the holding tube 50 is inserted while resisting the reaction force from the inner wall 66 of the holding hole 62, and is deformed radially inward by flexibility. It is done. In the inserted state, the holding tube 50 is firmly attached to the inner wall 66, and the protruding bar 38 and the holding tube 50 are prevented from falling out of the holding hole 62 in a free state.

  Further, the held protruding bar 38 and the holding tube 50 can be removed from the holding hole 62 by being pulled out with a sufficiently larger force than in the free state. At the time of removal, the holding tube 50 is pulled out from the holding hole 62 together with the protruding bar 38 while resisting the reaction force from the inner wall 66.

  The counterbore 64 has a square cross section and has a depth and a width to accommodate the L-shaped piece of the movable hinge piece 34. The center of the counterbore 64 may be the same as the center of the holding hole 62, but may be located slightly outside (outside in the left-right direction) than the center of the holding hole 62. The counterbore 64 has three side walls 70, 71, 72 excluding the inner side wall, and a bottom wall 74 that is continuous with one end of the three side walls 70, 71, 72 and is orthogonal thereto.

  The bottom wall 74 is brought into contact with the peripheral edge of the back surface 34 b of the movable hinge piece 34. By pushing the protruding bar 38 and the holding tube 50 into the receiving hole 60 until the contact, the final position of the insertion of the protruding bar 38 and the holding tube 50 into the receiving hole 60 is defined.

  In the inserted state at this final position, as shown in FIG. 5, the movable hinge piece 34 is concealed by the counterbore 64 in the hinge 20, and only the outer surface of the fixed hinge piece 32 is visible from the outside. Further, when the temple portion 12 is closed via the hinge 20 in this inserted state, a part of the inner portion of the fixed hinge piece 32 is accommodated from the open side wall inside the counterbore 64. It has become. That is, by cutting out the inner side wall of the counterbore 64, the temple portion 12 can be opened and closed without the hinge 20 being gripped by the receiving hole 60.

  Here, in this embodiment, the counterbore 64 has a square shape, and the outer side of the back surface 34b of the movable hinge piece 34 has a square shape so as to match the size of the square. Therefore, in the inserted state at the final position, The rotation of the temple portion 12 with respect to the hinge 20 is prevented. In other words, a rotation stopping means is formed in which the outer shape on the back surface 34b side of the hinge 20 is the engaging portion and the counterbore 64 is the engaging receiving portion, and both are engaged in the inserted state at the final position. By doing so, the temple part 12 will be in a rotation stop state. This prevents the temple portion 12 from rattling against the hinge 20.

The effect of the spectacles 1 demonstrated above is described.
First, in a state where the temple portion 12 is connected to the hinge 20 using the holding tube 50 (inserted state at the final position), the holding tube 50 contacts the inner wall 66 of the receiving hole 60 and the protruding bar 38 like a cushion. To do. Accordingly, direct contact between the inner wall 66 made of the shell and the metal protruding bar 38 can be avoided, so that wear of the inner wall 66 due to the direct contact can be prevented.

  Further, in this connected state, the protruding bar 38 is held in the holding hole 62 via the holding tube 50, so that it is possible to eliminate the need for an adhesive, and even if vibration is applied to the glasses 1 due to, for example, a human walking action. , It can be prevented from falling from the receiving hole 60. In addition, it is not necessary to make the depth of the holding hole 62 relatively large. Thereby, even if it is a case where a shell is used as a raw material of the temple part 12, the receiving hole 60 can be processed without being damaged.

  On the other hand, the protruding bar 38 allows the temple portion 12 to be handled separately from the hinge 20 and the front portion 10 because it is allowed to be extracted from the receiving hole 60 together with the holding tube 50. Thereby, while the temple part 12 can be replaced | exchanged alone, the hinge 20 and the front part 10 can be replaced | exchanged collectively. For this reason, repair of each part of the spectacles frame 2 is easy.

  Further, since the receiving hole 60 of the temple portion 12 made of Sakai shrinks with time, the inner diameter of the holding hole 62 also tends to be reduced. Thereby, the adhesiveness of the holding tube 50 in the holding hole 62 can also be improved over time, and the protruding bar 38 and the holding tube 50 are less likely to fall out of the receiving hole 60 over time.

  Furthermore, the temple portion 12 can be attached to the hinge 20 only by pushing the protruding rod 38 with the holding tube 50 attached into the receiving hole 60, so that the attaching operation can be simplified. In addition, after the attachment, most of the hinge 20 is not exposed to the outside in a side view from the outside shown in FIG. Therefore, the sense of unity between the front portion 10 and the temple portion 12 is enhanced, and the design can be improved.

<Modification>
Next, a modified example of the glasses 1 according to the above-described embodiment will be described.

  The projecting rod 38 may be formed in a square rod shape, the holding tube 50 may be formed in a rectangular tube shape correspondingly, and the holding hole 62 of the receiving hole 60 may have a rectangular cross section. By doing so, the protruding rod 38 and the holding hole 62 function as a means for stopping the temple portion 12, so that it is not necessary to form the counterbore 64 in the receiving hole 60, for example. However, considering the ease of processing and the like, it is preferable to make the cross section of the holding hole 62 circular as in the above-described embodiment.

  As the protrusion on the side of the hinge 20 to be inserted into the receiving hole 60, for example, a plate-like member can be used in addition to the protrusion bar 38 described above. However, also in this case, it is preferable that the projecting portion has a cylindrical shape in consideration of the ease of processing the holding hole 62.

  The holding tube 50 may not be removed from the receiving hole 60 together with the protruding bar 38 but may be continuously accommodated in the holding hole 62 after insertion. That is, even if the protruding bar 38 is pulled out from the holding hole 62 for replacement or the like, the holding tube 50 may be kept in close contact with the inner wall of the holding hole 62.

  Although a so-called full rim type frame is used as the spectacle frame 2, it may be a half rim type without the lower portion of the rim frame 14 or a rimless type front portion 10 without the rim frame 14 itself.

In the case of the half rim type, the front portion 10 has a bridge 16 and nose pads 18, 18 in addition to a pair of left and right blow bar portions. In this case, the hinge 20 is fixed to the blow bar portion.
In the case of the rimless type, the eyeglass frame 2 can consist only of the temple portion 12. In this case, the fixed hinge piece 32 of the hinge 20 is fixed to the lens 3.

  Further, as the eyeglass frame 2, it is possible to use a frame in which the temple portion 12 is not opened and closed with respect to the front portion 10 while the front portion 10 is connected to the temple portion 12 by connecting means. In this case, as long as the connecting means includes the receiving hole 60 of the temple portion 12, the protruding rod 38 of the connecting member fixed to the front portion 10, and the holding tube 50, the same action as the above-described embodiment. There is an effect. For example, the effect of being able to prevent the inner wall 66 of the receiving hole 60 from being worn while improving the exchangeability of the temple portion 12 and the front portion 10 and the workability of the receiving hole 60 can be achieved.

  The connecting means may include a receiving hole formed in the front 10, a protruding rod of a connecting tool fixed to the temple portion 12, and the holding tube 50.

< Reference example >
Next, the accessory using the connection structure in the spectacle frame 2 will be described. Examples of the accessories include brooches, pendants, earrings, earrings, bracelets, hair clips, loupes, and straps. Here, an earring will be described as an example.

  The earring is a decorative body (first member) formed from a shell, etc., a holding body (second member) for holding the decorative body, and an earlobe attached to the holding body directly or via another member Part. Earrings are attached to a person's ear by the earlobe mounting part holding the person's earlobe. The material of the decorative body is typically a shell, but of course, the materials of the front part 10 and the temple parts 12 and 12 described above can be used. Similarly, the material of the decorative body is preferably a shell, an animal horn, a tree, bamboo, and acetate. On the other hand, the material of the holding body is not particularly limited, and a metal can be used in addition to the shell.

  Such a decorative body and the holding body can be connected by the same connecting means as described above. Specifically, the connecting means includes a receiving hole formed in the decorative body, a protrusion in the holding body that is inserted into the receiving hole, and a holding member that is inserted into the receiving hole. The receiving hole, the protruding portion, and the holding member can be formed in the same manner as the receiving hole 60, the protruding bar 38, and the holding tube 50 described above, and these modified examples and additional structures (such as a locking means). Can also be applied as appropriate. Further, the protruding portion can be formed on another member that is integrated with the holding body or fixed to the holding body.

Therefore, according to the earring of the reference example , the workability of the receiving hole can be improved and the wear of the inner wall surface of the receiving hole can be suppressed even if a material such as a shell is used for the decorative body. In addition, since no adhesive is used for the connection structure, the decorative body can be handled separately from the holding body and the earlobe mounting portion, and the decorative body and the holding body can be replaced individually.
